Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional board connector and cable connector are inserted with each other, then the connection can be established, but the connection is prone to loosening due to external force
Solution Approach 1:
The elastic arm provides dynamic adaptability by deforming under external force and returning to its original position, allowing the connector to maintain stable electrical contact while accommodating external forces. The elastic deformation mechanism enables the connection to be both stable and resilient against loosening.
Solution Approach 2:
The L-shaped elastic arm with its curved geometry provides mechanical advantage and leverages elastic deformation principles. The curved structure allows the elastic arm to flex and absorb external forces while maintaining the electrical connection between conductive pillars and conductive members.
2Reliability
If locking mechanisms are added to prevent loosening, then connection stability improves, but device complexity increases
Solution Approach 1:
The elastic arm integrates multiple functions into a single component: it provides mechanical support, ensures electrical contact through its conductive nature, and acts as a locking mechanism through its elastic deformation. This merging of functions prevents loosening without requiring separate complex locking structures.
Solution Approach 2:
The elastic arm automatically locks the connection through its own elastic properties. When the connector is assembled, the elastic arm deforms and naturally maintains contact pressure, providing self-locking functionality without requiring additional locking mechanisms or complex assembly procedures.

AI summary
A connector assembly includes a board connector and a cable connector. When the board connector and the cable connector are inserted with each other, two conductive pillars of the board connector are inserted into two insertion slots of the cable connector, a board locking mechanism of the board connector is engaged with a cable locking mechanism of the cable connector, and the board locking mechanism and the cable locking mechanism are configured to jointly limit the board connector and the cable connector for enabling the board connector and the cable connector to be firmly connected to each other.
